Speed ratio calculation of a single stage gear train (Figure 2-3)įigure 2-3 : Mechanism of geared motor 4. Geared motor is an electrical part consisting of a small motor and a gear box to produce larger torque rather than to lower the motor’s rotational speed. Many geared motors are used in automotive parts, home appliances, and motors of industrial machines. (This point will be explained in the next chapter.) Therefore, the speed of a small output power of a motor is decreased with gears to produce larger torque in most cases.

The torque becomes smaller when increasing speed and becomes larger when decreasing. The rotational speed of the output shaft is decreased, increased or made the same compared to that of the input shaft depending on the purpose of the application. The aim of mechanism design with gears is to acquire the necessary rotational number by combining several gears. Speed ratio (speed increasing / decreasing ratio) 'CW and CCW are frequently appearing words in mechatronics product development and, therefore, important for you to remember !'ģ. Therefore, viewing directions need to be consistent when showing mechanism movement with pictures (Figure 2-2).įigure 2-2: Definition of the rotational direction of gears as seen from a predetermined viewing direction Unlike motors, the rotational direction of gears can be defined differently depending on the viewing direction.

Mechanical design engineers need to convey information about a motor’s rotational direction to electric design engineers and software design engineers. (Figure 2-1)īy the way, the spin to the right is commonly abbreviated as CW (clockwise) while the spin to the left as CCW (counterclockwise).įigure 2-1: Definition of the rotational direction of the motor

Rotational direction of the motor is defined by the rotation of the shaft as seen from the side the motor shaft projects out. Generally, a motor is used as the power source when using gears in designing mechanisms of mechatronics products. Let me explain this with commonly used cylindrical gears. You can change the directions and the number of rotations of the input and output shafts by meshing several gears. (Table 2-1)Ĭhange rotational direction (clockwise / counterclockwise)Ĭhange the number of rotations (speed up / down)Ĭhange turning force (increase / decrease torque) Here is the list of gear functions for mechanism designs.
